## Hide the subfolder from appearing in url

I want to move from `www.example.com/_/randomfolder` to `example.com/randomfolder`. It should acces the contents from `/_/randomfolder` but should show `example.com/randomfolder`.

What I have tried:

# Trial 1

``RewriteEngine On RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteRule ^(.*)\$   http://www.%{HTTP_HOST}/\$  1 [R=301,L,QSA] RewriteEngine On RewriteCond %{HTTPS} off RewriteRule ^(.*)\$   https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] ``

Problem: it full fills my requirement from `/_/randomfolder` but should show `example.com/randomfolder` but affects my main domain `example.com` it shows nothing, only a 404 page. I want it to show `public_html/index.php` only.

# Trial 2:

``RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d #To load site from  /_/xyz to /xyz  without hcanigng url RewriteRule ^[A-Za-z0-9._]+  /_/%{REQUEST_URI} [L] ``

Problem: I have to manually change the address bar from `www.example.com/_/randomfolder` to `example.com/randomfolder`, it load contents with or without `_` but on first time load its redirects to `/_/random folder`.

## Why aren’t my hero images appearing as thumbnails in the SERP?

I display hero images across the top of my blog pages. However, I use CSS images rendering through div tags and I read that google doesn’t typically index those.

So the images aren’t included as thumbnails in SERPs, see below.

Can you please confirm if there is a way to direct google to index the images like with an image sitemap?

Does an image have to be included in the IMG tag to be considered for a thumbnail in the SERP?

## News not appearing in News-Webpart and Sites not appearing in Activity Webpart

Basically what the title says. I can add a news site in my SharePoint 2019 Server, but it will not appear in any of the webparts. It is shared as a news article, it is also readable by all users.

I already tried starting manual re-indexing. I also tried giving the users all kinds of additional permissions, but so far nothing worked.

I also noticed that I can not see the webpart options such as “news sources” for the news-webpart, that I have seen on various tutorials.

I can also not choose any lists from the list-webpart, but I am not sure if this is the same issue.

## Mails sent from the command line not appearing in inbox or spam folder

I sent some test mails using the command line. In the log I can see that `status = sent`, but I am not getting any emails in my inbox or spam folder.

## Ubuntu and Windows Partitions Appearing Under the Same Name

I’m trying to install Ubuntu on my SSD along Windows 10. I started by installing Windows 10, disabling fast boot and then trying to install Ubuntu. I created a Swap of 16gb. Ubuntu told me I needed an EFI so I created one of about 100 mb. The root took the remaining space. However when I restarted my computer I don’t see any partitions, and simply see this: (https://i.imgur.com/6RTFWBB.jpg). If I click the hard drive it’ll just say no os found.

I went back to check the partitions through the Ubuntu installer and see this: https://i.imgur.com/3ZcVeLN.jpg

It looks like the partitions were installed correctly, but I’m not getting a proper boot loader to choose between windows and Ubuntu. What should I do?
